Arisudan's place is by far the best value for money I found so far in Bangkok! The place is freshly renovated and spotless clean. It has two big rooms, one bedroom and one living room as well as a separate bathroom and balcony. Big wardrobe, big fridge, big and comfortable bed. Couldn't be better. It's an ideal place to stay for a few days an explore the city or even for long term and do work. BTS On Nut is just 2/3 min with moto and from there you can get anywhere.
Very friendly host, responsive, good english and helpful. Thanks mate, will be back soon ! :)
